Its possible that your servo could be dead. When you by pass the gyro and connect to ch4, I want you to remove the servo arm from the servo and reposition the arm on the servo so that the arm and the servo case is 90 degree and perpendicular to each other. Does the servo still going only right? did you make sure your rudder trim is at the center?

ok so i loosened the boom from the frame, pulled it back and tightened it back in....that fixed the slipping problem. But still cant get the rudder to work correctly. I have right rudder but no left. After the heli initializes and the tail rotor centers, i get no response from left rudder. I unplugged the tail rotor servo bypassing the gyro and plugged into #4 on the receiver and the same thing happens! no left! What can be going on?
